Frequently Asked Questions
Why are you so much cheaper than others?
Most test analytics platforms charge per test run or per test result. We don't.
The Flakiness.io team comes from Microsoft Playwright project, which runs 300,000+ tests on every commit and pull request, with hundreds of commits per month. At that scale, per-test-run pricing from existing providers was prohibitive, and we weren't confident they could handle the volume at all.
Flakiness.io uses a custom test analytics engine, optimized for massive workloads. It's so efficient that our costs scale with storage, not compute. So that's exactly how we charge: you pay only for uploaded reports, not per test or per test run.
Besides, charging per test feels wrong: it penalizes teams for writing and running more tests. We want to encourage more testing, not make you think twice before adding a test suite.
What's with the name?
When we started building Flakiness.io, test flakiness was our main focus. We researched how to properly detect it and adopted an approach based on a white paper from Apple engineers , the flip rate metric. The key insight: a test is only truly flaky if it changes its outcome across runs on the same commit and environment.
But as we dug deeper into test analytics, we realized there's so much more you can do with historic test data: duration trends, pull request regression detection, agentic workflows, performance testing and more.
The name stuck, though.
Who develops test runner integrations?
The Flakiness JSON Report format is open source, so anyone can build their own reporter.
That said, we also maintain official reporters for Playwright Test, Pytest, Vitest, CucumberJS . All open source under the MIT license, built by the same team that builds the platform, so they're always up to date and deeply integrated.
Can I host Flakiness.io on my own servers?

Who's Behind Flakiness.io
A Decade of Building Dev Tools
Flakiness.io is created by Andrey Lushnikov, who spent over a decade at Google and Microsoft building the tools that testing engineers rely on every day: creating Google Puppeteer and co-founding Microsoft Playwright.
After years of dealing with flaky tests and fragmented test reporting, he built the tool he wished existed.
